Just looking for clarification here as I can’t quite tell what its asking for.
cats[4] would return whatever is in index
#4 of the variable which is what I assume the “element value” would be.
If there’s a string “cats” stored in cats then cats[4] would be invalid/out of range and probably return null, right? But that’s assuming the variable cats is exactly “cats” when cats could be literally anything.
Since the question doesn’t say what is stored in cats I assume its asking for what index its pointing to (4) or what position the content is in a list if you started at 1. like if you have
cats = "catsrule" then cats[4] = r , the 5th letter in the string. Which is the element value? I tried looking up the term “element value” to see if it has a specific definition but I got mixed results. I feel the question could be better asked with “here is a string, here is a declaration, what does it display/return?”.
An array element value refers to the specific data stored at a particular position within an array.
We can’t know that, as we are not privy to the cats array’s contents.
I think the question is asking which element in the cats array is being referenced with cats[4] ?
Do you find this wording more clear?
Kinda? If element value is the specific data stored at a position then its still not clear what its asking for imo.
Say there’s an array [A,B,C,D,E]
and you print array[4] it would print E
Is “E” the element value because that’s the data stored at that position, or is it 5 because its the 5th item in the array, or is it 4 because we start the count from 0 akin to index?
Given array[A,B,C,D,E]
There are 5 array elements and 5 index values (0-4).
For array[4]:
The array element is E, the index value is 4, and E is the fifth array element
Thus for cats[4]
Which array element in the cats array is being referenced with index 4?
The real point of the question is “do you know that index values start at 0”.
